custom Form data

[mosabsomaer]

ive been dealing with this problem for a week now
im trying to find a way to put form data in the post request of the file but i cant find a method there is only one thing about form data in this package which is this
paramName

Type: String
Required: false
Default: file

Formdata key for file upload request

but thats only to name param
while i have these form data

"acl": "private",
"key": "6e24c408-172e-41fd-a818-ff6dbdc6c2f9/${filename}",
"success_action_status": "201",
"X-Amz-Credential": "cloudconvert-production/20240624/fra/s3/aws4_request",
"X-Amz-Algorithm": "AWS4-HMAC-SHA256",
"X-Amz-Date": "20240624T104853Z"

   although ive spent weeks trying to understand and make this package work perfectly i  even hardcoded its css to remove stuff that i didnt want 
   and now im thinking there is no way to put in form data so imma have to find another package
